Many of us use a car to travel to work / school. The machine saves a lot of time. But if a flat tire, it's a long time. You can solve the problem - use compressors to inflate the tires of the car. They will create working pressure in the tire in a couple of minutes. And even if you have a small puncture, you may well be able to get to the tire fitting without a tow truck. Let's look at what characteristics this device should have and how to choose it correctly. Air auto-compressors for inflation of tires today are one of the essential accessories in the car. It is with the help of these devices that one can easily repair a broken or flat tire on the road. This is a very useful thing.
Main technical characteristics of car compressors
In fact, there are few characteristics, but they must be taken into account. If you pick up the device incorrectly, then it simply will not be able to pump a specific wheel on a particular car. The most important characteristics are productivity, maximum and working pressure, the presence or absence of a pressure gauge.
Performance
Compressors for pumping car tires vary in power. This indicator is indicated for each model and is measured in liters per minute. For example, if the label indicates a productivity level of 30-40 l / min, then such an apparatus can inflate a 13-14 ”tire in a passenger car in a few minutes.
For off-road vehicles, as well as for crossovers that differ in larger diameter wheels, it is recommended to choose equipment with more power. Recommended characteristic - from 50 l / min. Often, manufacturers do not provide information on how to understand this performance indicator - this is the speed of filling a certain amount of air or the volume under pressure.
Pressure
Compressors for inflating the tires of a car differ in this characteristic. So, the maximum operating pressure is up to 8 atm. However, when choosing, it is not recommended to proceed from this maximum value. In addition, the market often offers models that do not correspond to the value declared by the manufacturer.
In stores you can find inexpensive equipment, where in the passport data the figure is 20 atm. For portable devices (and these devices are portable), creating such pressure is simply not realistic. Even the wheels of KamAZ have a peak pressure of 8 atm, and here as many as 20.
Pressure gauge
Air auto-compressors for inflation of tires can be equipped with a pointer or digital pressure gauge. This is an important device. The accuracy of the pressure that will be pumped into the wheel is of great importance. Many domestic and imported instruments are equipped with sufficiently accurate measuring equipment with minimal error. Its scale on devices of various price categories is well read and convenient to use. Pressure gauges are divided among themselves according to accuracy classes. This is 0.2, 0.6, 1.2, 2.5, 4.0. The smaller the class, the higher the accuracy of the measuring device.
Features of mechanical pressure gauges
On such a device, most often there are two scales for different units of measurement. So, there is a scale in pounds per inch squared, and there is atm. The scale is rated at 300 psi. Thus, the manufacturer creates the illusion of power - often, the units do not have such performance. But the accuracy of such a scale is quite low even in the range from 2 to 2.5 atm.
For your own peace of mind, it is better to control the
pressure level
in the tire using a separate pressure gauge. On these measuring instruments, the scale is more informative.
Digital pressure gauges
These devices are more convenient and practical, unlike analog ones. Pressure is measured with high accuracy. During operation, there is no image vibration, and you can also change the unit of measurement. Another advantage is the presence of a start-stop system. The car owner sets the desired pressure on the scale and the device will simply turn off when this pressure is reached.
Differences in Type of Nutrition
Also, compressors for pumping car tires vary in type of power.
They can operate from the network and have more power. There are cigarette lighter units on sale. Their power is often small. There are also devices equipped with a battery.
Useful Options
Choosing automobile compressors for inflation of tires, it is necessary to pay attention not only to the performance or accuracy of the pressure gauge. Ease of use is not in the last place. Indeed, most often motorists pump up wheels, but rarely inflate them completely. A useful feature would be the ability to pump out air - sometimes it is necessary to pump out air from air mattresses or boats. The device can also be equipped with a bleed valve. This allows you to most conveniently lower the pressure in the tire. Another useful option is automatic shutdown when overheating.
Now both imported and domestic units are equipped with a large number of nozzles. Adapters help to pump up not only the wheels of cars, but also balls, boats, as well as other things that people use in everyday life. A boat nozzle for a tire inflation compressor will appeal to fishing enthusiasts.
Selection tips
Professionals recommend purchasing a device with a metal case. This equipment has a longer service life. The plastic case must withstand low temperatures. This also applies to connecting hoses.
The power cable must be at least three meters long. It is best if the wire is as solid as possible - without cracks and other defects. As for the nozzle, experts advise the threaded version. Information for those who are going to buy a compressor for pumping tires: the price of these units is from 1300 rubles and above. There are models of domestic and foreign production.
